The United States has flown a B-1B supersonic bomber over South Korea in part of a massive combined aerial exercise involving hundreds of warplanes, a clear warning after North Korea last week tested its biggest and most powerful missile yet.

Military officials say they plan to move ahead with large-scale U.S.-South Korea exercises later this month that North Korea, which is finalizing plans to launch a salvo of missiles toward Guam, claims are a rehearsal for war.

On the eve of his first meeting with Russian President Vladimir Putin, President Donald Trump vowed Thursday to confront "new forms of aggression" targeting the West and called for Moscow to stop fomenting unrest around the world.
